Why do ammeters are connected in series?
Why do voltmeters are connected in parallel??
Why do voltmeters have more resistance?
Answers
Answer:
A voltmeter has very high resistance and if it is connected in series then it would consume all the current and an ammeter has low resistance and if it is connected in parallel then all the current would flow through ammter and negligible in the circuit .

Answer:
1) In order for an ammeter to measure a device's current, it must be connected in series to that device. This is necessary because objects in series experience the same current. ... Ammeter in Series: An ammeter (A) is placed in series to measure current. All of the current in this circuit flows through the meter.
2) A voltmeter is an instrument that measures the difference in electrical potential between two points in an electric circuit. ... In order for a voltmeter to measure a device's voltage, it must be connected in parallel to that device. This is necessary because objects in parallel experience the same potential difference.
3) A voltmeter is a device to measure the voltage between two points in a circuit. It should not change the amount of current flowing in the element between the two points. When the voltage has high resistance it will not draw current from the circuit.
